The depth of cutshould be smaller

than the noseradius value.

If the cutting edge crosses the centre line of a work piece, the cutting edge can fracture.

With depths of cut larger than the nose radius value, burrs will be formed.

MICRO-DEXaWe recommended using cutting fluid to improve tool life and accuracy of the machined surface.a Indexable inserts and clamp screws are small and can easily be lost.a If the insert screw is overtightened, the screw or wrench may be damaged. Follow the guidelines shown below when tightening the clamp screw. The appropriate insert tightening torque is 0.5 (N/m).

Tightening of insert screw Screw tightening without an insert

zHold the wrench flag as shown in the diagram and turn it until finger tight.

The main screw part may be damaged if tightened.

xHold the wrench flag and turn it approximately 60° to 90° (reference tightening angle).

Correct Incorrect

aNote that the procedures are performed starting with the insert screw on the back side when using a reverse holder.

Normal use Reverse holder use

Start with the insert clamp on the front side. Start with the insert clamp on the back side.

Insert easily falls out

a If the holders break, Mitsubishi Materials can repair them.

MICRO-MINI TWIN

Repair

aUse within recommended specification ranges. Maximum L/d=5 (L : total length; d : shank diameter) If the L/d ratio exceeds the recommended value, lower the cutting conditions.

3rd clamping screw

2nd cutting edgeInsert point

The reference plane of a square type holder

Tighten the clamp screws making the micro-mini twin boring bars contact with the reference plane of the square type holder.

Fig. 2

Fig. 3

aTo avoid chipping of the 2nd cutting edge take care when inserting the boring bar into the holder. Refer to fig.1. If the 2nd edge contacts the internal face of the holder there is a possibility that it may chip.

aWhen installing the boring bar into the holder, tighten the clamp screws after ensuring the flats on the tool holder are parallel to the reference flats on the micro-mini bar. Refer to fig.3.

sMake sure that the clamping screws are tightened to the recommended values.

dDo not tighten the clamp screw without a bar in place, otherwise the bridge will be deformed.

sWhen using this type of holder, there is a possibility that damage to the shank and the 2nd cutting edge can occur. Make sure that the clamping screws are tightened to the set torque value. Additionally make sure that there is no clamping screw near the 2nd cutting edge as this can break the boring bar.

eWhen using Mitsubishi holdersWhen using holders with a tool overhang of recommended quantity, ensure that the 3rd clamping screw is removed prior to machining. The set torque value for clamping screw is 2.0 N•m.

aWhen using a holder for general purpose / small automatic lathe.

Problems related with poor chip control were eliminated.

Conventional tools with a flat land on the rake face caused high cutting resistance and tended to break. The sharp edge of the Micro Mini Twin improves cutting edge reliability.

Conventional tools left burrs on the thread, whereas the Micro Mini Twin with a chip breaker left no burrs.

For Your SafetyaDon't handle inserts and chips without gloves. aPlease machine within the recommended application range and exchange expired tools with new ones in advance of breakage. aPlease use safety covers and wear safety glasses. aWhen using compounded cutting oils, please take fire precautions. aWhen attaching inserts or spare parts, please use only the correct wrench or spanner. aGrinding or heating of cutting tools produces dust and mist. Inhaling large amount of dust or contacting with eyes and skins may harm your body.
